Summary
Venetoclax is used to treat certain blood cancers, such as chronic lymphocytic leukemia, which is a type of cancer that affects white blood cells, and small lymphocytic lymphoma, which is a similar cancer affecting lymph nodes.
Venetoclax works by inhibiting a protein called BCL-2, which helps cancer cells survive. By blocking this protein, Venetoclax causes cancer cells to die, effectively reducing the number of cancer cells in the body.
The usual starting dose of Venetoclax for adults is 20 mg once daily, gradually increasing to a maximum of 400 mg daily. It is taken orally with a meal and water, following the doctor's specific dosing instructions.
Common side effects of Venetoclax include fatigue, which means feeling very tired, nausea, which is feeling sick to your stomach, and diarrhea, which is having loose or watery stools.
Venetoclax can cause tumor lysis syndrome, which is a rapid release of cancer cell contents into the blood, leading to serious issues. It is not recommended for people with severe liver problems or during pregnancy.
